HOPPER FoR' FEED-GRINDERS.

SPECIFICATION formingpart of Letters Patent No. 226,337, dated April 6,1880.

Application filed August 9, 1879.

To all whom it may concern Be it known that I, GEORGE IVIETOALF, ofLeland, in the county of La Salle and State of Illinois, have invented anew and Improved Feed-Grinder, of which the following is aspecification.

Figure l is a plan of the grinder. Fig. 2 is a sectional side elevationon line 00 00. Fig. 3 is a sectional end elevation on line y y.

Similar letters of reference indicate corresponding parts.

The object of this invention is to provide a cheap and simple machinefor grinding feed for cattle, horses, &;c., that is designed moreparticularly to be operated by windmills having a crank motion.

A is a standard that supports the two stout timbers B B, that constitutethe frame-work of the machine. At one end of the machine these timbersand the vertical beams of the standard are bolted firmly together by thebolt a, and at the other end the side pieces of the frame are heldbybolt 1), on which the lever G is pivoted. Secured to the inner faces ofthe side pieces, B B, are the corrugated or grooved grinding-plates d(1, while on either side of the lever corresponding grinding-plates f fare fastened. Immediately over these plates, and large enough to coverthem, is a hopper or box, D, for the reception of the feed to be ground.A side of the box is attached in an upright position to each side piece,B B, while the ends are secured in proper position on the lever O. Theends of the box-sides and the ends of its ends are turned inward atright angles, as shown at g g and h h, so as to better hold the grain inthe box or hopper while the machine is in operation.

Preferably the grain is fed into the machine through a tube leading froma hopper ata higher elevation, in order to prevent as much as possibleloss of grain through the corners of the hopper D.

When the machine is in operation the grain or feed put into the hopperfalls between the lever grinding-plates and the side grindingplates, andis crushed and ground between them by the np-and-down reciprocatingmotion of the lever, discharging finally into any receptacle placedunder the machine.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- The combination, with frame B and lever C, ofthe hopper D, having the ends of the ends and sides turned inward at gh, as and for the purpose specified.

GEORGE METOALF.
